Interpreting fullstimer

[NDakota]

Hi, I'm working on a SAS/Unix system having serious performance issues. I've run a couple of jobs with fullstimer turned on to get some idea of where the bottleneck is. Is there an ideal ratio between voluntary/involuntary context switches? Some of the data steps seem to have a ratio of at least 1:20.

Any help is much appreciated before I talk to the Unix admin.

Try increasing your sort size (in the config file). If you're running SAS Share you may need to start and stop the service once in a while.

Last but not least you should to have a SAS programmer go over the code and try to 'clean-up' the code so that redundant steps are not implemented.

An example of the above. I recently went back to some programs I wrote a few years back and found that I SORTed a table so that I could JOIN it to one data value in another table. Now, with the use of the HASH object this sort is not needed. Eliminating these types of steps could speed up both the run-time and execution of some older programs.
